Male house crickets reared individually at 28 °C developed a diel periodicity in spermatophore formation, which consisted in loss of the spermatophore during the dark period and secretion during the light period. The periodicity became established only after most of the insects had formed at least two spermatophores in a random way with respect to light conditions. When periodicity was established, rearing the insects in continuous light resulted in the retention of the spermatophore by nearly all insects. Stridulation began in all experiments at the time of first spermatophore formation.

Food And Feed

The Kjeldahl method is the most utilized method for total protein content analysis in food. Using the universal nitrogen-to-protein conversion factor of 6.25, the protein content of insects is likely to be overestimated due to their chitin content. We have calculated nitrogen-to-protein conversion factors for two crickets, house cricket (Acheta domesticus) and field cricket (Gryllus bimaculatus), which are used for food and feed in Europe. By analyzing their nitrogen and amino acid content we were able to show that a conversion factor of 5.09 could be used for house cricket and 5.00 for field cricket in protein content calculation. Based on these results with a reservation about slight variation in farming conditions, we suggest a nitrogen conversion factor of 5.0 for both crickets.

Gryllus Integer

Many female insects mate more than once although the adaptive significance is often unclear. We studied the frequency of mating, the fate of the spermatophore, and progeny production of individual females as a function of single or double matings in the house cricket, Acheta domesticus, and the field cricket, Gryllus integer. Females of both species may mate repeatedly and often eat the externally attached spermatophore. In A. domesticus, doubly mated females produced significantly more offspring than did single maters, the difference resulting largely from the failure of 12.5% of the single maters to leave progeny. Singly and doubly mated G. integer did not differ regarding nymph production, but 50% of the singly mated females did not reproduce. Remating by female crickets partly functions in offsetting the probability of a failed initial mating. Nymph production increased significantly with the time the spermatophore was attached in singly mated A. domesticus. Spermatophore consumption by the female was not affected by male "guarding" behaviour, and the interval between mating and eating of the spermatophore may often be shorter than the time required for maximum insemination. It is suggested that acquisition of nutrition may be an additional function of female repeated matings.

Bean Beetle

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
